Analysis of Solar Active Regions and Activity from 08/2100Z to 09/2100Z: Solar activity was very low. Region 933 (S06W56) developed several new spots in the northwestern portion of the spot group. No new regions were numbered today. IB. Solar Activity Forecast: Solar activity is expected to be very low with a chance for isolated C-flare activity from Region 933. IIA. Geophysical Activity Summary 08/2100Z to 09/2100Z: The geomagnetic field was quiet. The greater than 2 MeV electron flux at geosynchronous orbit reached high levels today. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be mostly quiet. III. Event Probabilities 10 Jan-12 Jan Class M 05/05/05 Class X 01/01/01 Proton 01/01/01 PCAF green IV.
